Indeed, metastatic triple-negative breast cancer (TNBC) cells maintain a high level of ATP production through the activation of mitochondrial FAO and carnitine-palmitoyltransferases 1 and 2 (CPT1 and CPT2), trans-membrane enzymes located in outer and inner mitochondrial membranes, respectively [201,202]. Here, CPT2 is linked to triple-negative breast carcinoma.
